ont my invention by employing a braiding machine similar to that shown and described in my Patent No. 1,081,474, Dec. i6, 1913, which is capable of producing di derent patterns in one continuous strip of fabric.

Referring to Fig. 2, it will be noted that the main portion L of the lacing is shown having a pattern generallyknown as basket braid, while the tip portion Thas a different pattern as now described. In the portion 'L of the braid the yarns cross each other at substantially right angles, passing over and under each other in pairs, while in the tip port-ion T the yarns are shown as crossing each other at very much greater angles so that they lie more nearly parallel to edge of the fabric. in other words, thev yarns 'in thetip portions T have a greater lead or pitch and therefore are compacted more closely and firmly to reduce the. size of`the fabric and give the desired. hard, rope-like structure to the tip of the lacing. To prevent the ends of the tips from fraying or raveling after the lacings are cut apart prefer to coat them-with a vwaterproof covering of shellac, varnish, glue, cement, enamel or other suitable com-- pound which will amalgamate the structure of the fabric and alsoadd to its stlffness.

`I have found in practice that shell-ac is well adapted to this purpose since it hardens quickly and is impervious to heat, cold and moisture.

It will be seen from 'the' above that my improved process of manufacture produces a lacing having terminal tips formed integral with the main portion and presenting a particularly neat and finished appearance.

By dispensing with the usual applied tips my improved lacing is made 'more durable, since metal tips are liablev to become detached in use and are frequently crushed and bent out of shape from being stepped upon. Furthermore, it has been found well nigh Yimpossible to enamel or color metal tips with permanent coating so that they soon become Worn and shabby looking.

Heretofore in manufacturing lacings it hasbeen necessary to first braid the. fabric and then either supply or form the tips by seine other process. l-Vith my improved process the complete lacing can be produced in the same machine, the tips being fashioned as )'iart of the braiding operationrand the operation of cutting the lacings apart and dipping their ends being accomplished by suitable devices operating in conjunction with the braiding mechanism. 'In this way ll not only greatly chcapeu the cost of manufacture but I also improve the appearance and finish of thc article.

lt will be mulcrstoml that l (le not herrin claim the improved lacing itself. the same bring the subject of a separate applicaiion tiled concurrently herewith. -lt is further Y facturing lacings consisting in intermeshing fibrous strands to form a continuous tubular strip of fabric and changing at predetermined intervals the pattern to compact the strands forming portions 'of reduced cross A'section adapted to serve as tips.

The herein described process of manufacturing lacings consisting in intermeshing fibrous strands to form a continuous tubular strip of fabric' and changing at -predetermined intervals the pattern to compact the strands forming portions of reduced cross section adapted to serve as tips, and severing said strip insaid reduced portions.

3. The herein described process of manufacturing lacings consisting in intcrmeshing fibrous strands with relative looseness to form a continuous tubular strip and changing the intermeshing operation at intervals to bring the strands more closely together to' form a hard round cord of less diameter' than the tubular portion adapted to serve as a tip.
